Description
I called setAuthenticationMode(1,0,0) in my program and a linking error occured.
I guess it's a static variable but only defined in the headers but not in .cpp files. Adding uint8_t BLESecurity::m_authReq; to BLEScurity.cpp:39 fix the link error, but i don't know if it runs well.
Sketch
#include "BLEHIDDevice.h"
#include "BLECharacteristic.h"
void setup() {
BLESecurity* pSecurity = new BLESecurity();
pSecurity->setAuthenticationMode(true);
}
